1) Matter a) Anything that has mass and takes up space b) The smallest unit of matter (too small to see) c) Does not change chemical composition. 2) Atom a) Something that takes up a specific amount of space, but does not have its own shape because it takes the shape of its container. (ex. Water, milk, orange juice) b) Does not change chemical composition. c) The smallest unit of matter (too small to see) 3) State of Matter a) A property that describes whether the material is a solid, liquid, or a gas solid Something that has a definite shape and takes up as specific amount of space (ex. Book, table, pencil) b) Something that has no definite shape, but will fill up any available space in the container it is in(ex. Air in a balloon) Something that has no definite shape, but will fill up any available space in the container it is in(ex. Air in a balloon) c) How easily a smooth surface can be scratched 4) Physical Property a) Does change chemical composition. b) Does not change chemical composition. 5) Material a) The ability of a substance to change into a new substance with different properties b) The matter from which a thing is or can be made c) Chemical property 6) Chemical property a) The amount of space an object takes up b) The matter from which a thing is or can be made c) The ability of a substance to change into a new substance with different properties 7) Volume a) The amount of matter in an object or substance b) The amount of space an object takes up c) The matter from which a thing is or can be made 8) Dissolve a) The amount of matter in an object or substance b) The ability of a solid to dissolve in a liquid c) To interact with and spread out evenly in the water 9) Solubility a) To interact with and spread out evenly in the water b) The ability of a solid to dissolve in a liquid c) A measure of a substance's ability to allow heat energy to pass through (usually made of metal) 10) Insulators Materials a) A measure of a substance's capability to allow electricity (energy) to pass through b) The amount of matter packed into a specific volume c) That slow or stop the flow of energy 11) Electrical Conductivity a) That slow or stop the flow of energy b) A measure of a substance's capability to allow electricity (energy) to pass through c) The amount of matter packed into a specific volume 12) Magnetism a) A force that pulls (attracts) magnetic materials across a distance (magnets) b) The amount of matter packed into a specific volume c) That slow or stop the flow of energy 13) Reflectivity a) A measure of a substance's ability to allow heat energy to pass through (usually made of metal) b) The ability of a solid to dissolve in a liquid c) A measure of an object's ability to bounce energy waves off the surface (mirror) 14) Liquid a) How easily a smooth surface can be scratched b) Something that takes up a specific amount of space, but does not have its own shape because it takes the shape of its container.
